Abstract (en)

[origin: EP2502800A1] The invention relates to a detector (10; 20; 30) for detecting a movement of a railway vehicle in a powerless time interval. At the beginning of the time interval, indicator items (7) or first magnetic antagonists of detection cells (4.1, 4.2, 4.3) are lifted by actuators (5) to a switching device (11), which provides at least one holding section (HS) or second magnetic antagonist for a part of the indicator items (7) which then stick to or near to the switching device (11) by magnetic force. The switching device (11), though, is movably mounted and coupled to the railway vehicle's movement, so the holding section (HS) moves relative the detection cells if the railway vehicle moves. As a result, detection cells (4.1, 4.2, 4.3) from which the holding section (HS) moves away experience a drop of the indicator item due to gravity (G). By means of sensors (6), such a drop can be detected at the end of the time interval and used for cold movement indication.
